203 bonded bridges were reinserted under standardized conditions. In 44 cases there was a loss of primary retention and in another 22 cases the bridges were removed for repair of a pontic. The bridges reinserted after loss of primary retention were significantly less successful (26%) than the bridges with primary retention (87%). The success rates of the bridges reinserted after deliberate removal (91%) was significantly higher than that of the bridges reinserted after loss of primary retention (48%).
203 个粘结桥在标准化条件下重新植入。44 例出现初始固位丧失，另有 22 例因修复桥体而移除粘结桥。初始固位丧失后重新植入的粘结桥成功率（26%）显著低于具有初始固位的粘结桥（87%）。有意移除后重新植入的粘结桥成功率（91%）显著高于初始固位丧失后重新植入的粘结桥（48%）。
